摘要
根据灾后重建地区血液保障体系建设的实际情况,考虑血站间的依附系数对血站布局的影响,建立了一种p-中值模型用来解决新增血站的选址问题,并设计了一种遗传-禁忌混合算法对模型进行求解。之后以汶川大地震灾区——四川省阿坝州为例进行了实例分析,得到了不同p值与依附系数下的新增血站选址方案,以期为相关部门规划灾后重建地区的血液保障体系提供理论依据与决策参考。
According to the actual situation of blood supply system in post-disaster reconstruction areas and considering the dependent coefficient among blood banks,a p-medium model is developed for the facility location problem of new blood banks.And a hybrid genetic algorithm combining with tabu search is proposed to solve the model.A case study is given based on one of affected areas in Wenchuan earthquake,i.e.Aba prefecture in Sichuan province.The location results with different p value and dependent coefficients are obtained as a reference for related departments to plan the blood support system in post-earthquake reconstruction areas.
